Q-260 FLUOROELASTOMER 75 Q RING

The QV70260 is an AS568-260 black Viton® (FKM) 75 Shore A Quad-Ring measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

As a material, Viton® (FKM) is specified for very low compression set at elevated temperature and outstanding high-temperature capability. The material holds up against chlorinated solvents, aggressive chemicals, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in low-molecular-weight organic acids or hot water and steam. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

Common environments for this compound include high-temperature process equipment, aerospace, and semiconductor equipment.

QV70260 ships individually. Unit weight is approximately 10.684 g and nominal inside diameter is listed as 6 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
